Is the calligraphy major in high school good? Now I'm a freshman.

If you want to learn calligraphy, you should learn it from an early age, so that the foundation will be deeper. If you just started learning in high school, I think if you don't like calligraphy very much, you should learn it early. Especially, the earlier you learn soft pen calligraphy, the less you can learn hard pen calligraphy. He will learn slowly in high school. If he really likes writing, he can still learn.
